Nonvolatile Memory Adaptive to Host Boot Up Routine

摘要

A nonvolatile memory that stores boot data from a host learns which data is boot data by monitoring read commands received from a host during a powering up operation. Boot data is then arranged in a manner that makes subsequent reading of the boot data faster when it is accessed during a subsequent powering up operation.

主权项

1. A method of operating a nonvolatile memory comprising:
monitoring a series of read commands received from a host during a first powering up operation to identify data stored in the nonvolatile memory that is used by the host during the first powering up operation; determining physical locations in the nonvolatile memory at which the identified data is stored; subsequently reconfiguring at least some of the identified data to provide reconfigured data with faster read access time than unreconfigured data; and subsequently, during a second powering up operation, accessing the reconfigured data so that the second powering up operation is faster than the first powering up operation.
